• The presence of antimicrobial-resistant in poultry is a growing public health concern worldwide due to its potential for transmission to humans. The aim of this study was to determine the prevalence and patterns of antimicrobial resistance and to detect drug-resistant genes in and in poultry from four districts in Zambia. Identification of was conducted using phenotypic methods. Antimicrobial resistance was determined using the disc diffusion method and antimicrobial resistance genes were detected using polymerase chain reaction and gene-specific primers. The overall prevalence of was 31.1% (153/492, 95% CI: 27.1-35.4). had a significantly higher prevalence at 37.9% (58/153, 95% CI: 30.3-46.1) compared with , which had a prevalence of 10.5% (16/153, 95% CI: 6.3-16.7). Most of the and isolates were resistant to tetracycline (66/74, 89.2%) and ampicillin and erythromycin (51/74, 68.9%). The majority of isolates were susceptible to vancomycin (72/74, 97.3%). The results show that poultry are a potential source of multidrug-resistant and strains, which can be transmitted to humans. Resistance genes in the species can also be transmitted to pathogenic bacteria if they colonize the same poultry, thus threatening the safety of poultry production, leading to significant public health concerns.
